Abstract (en)
A vehicle having a diagnostic system for a fuse is provided. The vehicle has first and second voltage sensors, a current sensor, and a microcontroller. The first and second voltage sensors generate first and second signals, respectively, indicating first and second voltage levels, respectively, at first and second ends, respectively, of the fuse. The current sensor generates a third signal indicating a current level flowing through the fuse. The microcontroller determines first and second voltage values based on the first and second signals, respectively, a current value based on the third signal, and a first resistance value utilizing the first and second voltage values and the current value. The microcontroller generates a diagnostic signal indicating degraded operation of the fuse if the first resistance value is greater than an end-of-life resistance value.
